Inclusion criteria

Inclusion criteria: Histologically or cytologically confirmed diagnosis of advanced/metastatic solid tumors. Has at least 1 accessible lesion with a minimum lesion diameter (>=1 cm) for injection of BI 1831169. Lesions must either be easily accessible, or, if not easily accessible, patients must be willing to undergo repeat procedures for injections of BI 1831169. Has failed conventional treatment or for whom no therapy of proven efficacy exists or who is not eligible for established treatment options. Patients must have exhausted available treatment options known to prolong survival for their disease. Medically fit and willing to undergo all mandatory trial procedures. ECOG Score of 0 or 1, and life expectancy of at least >=3 months after the start of the treatment, according to the investigator's judgement. Adequate organ function or bone marrow reserve as demonstrated at screening by the following laboratory values: Absolute neutrophil count >=1.5 x 10^9/L (>=1.5 x 10^3/uL, >=1500/mm3) without white blood cell growth factor support within 4 weeks of start of trial treatment Platelet count >=100 x 10^9/L (>=100 x 10^3/uL, >=100 x 10^3/mm3), without platelet transfusion within 2 weeks of start of trial treatment Hemoglobin >=90 g/L (>=9.0 g/dL, >=5.6 mmol/L) Creatinine =18 years of age at the time of signature of the ICF. Further inclusion criteria apply.

Exclusion criteria

Exclusion criteria: Major surgery (major according to the investigator's assessment) performed within 4 weeks prior to start of trial treatment Radiotherapy within 4 weeks prior to the start of trial treatment, except in case of a brief course of palliative radiotherapy (e.g. for analgesic purpose or for lytic lesions at risk of fracture) which can then be completed within 2 weeks prior to start of trial treatment. Note: No radiation must have been given to any lesions planned to be injected within 6 months of start of treatment. Presence of brain metastases unless patient has completed brain radiotherapy and is asymptomatic. Symptomatic brain metastases, untreated malignant brain tumors and/or carcinomatous meningitis are excluded. Presence of other active invasive cancers other than the one to be treated in this trial within 3 years prior to screening, except for appropriately treated basal-cell carcinoma of the skin, in situ carcinoma of the uterine cervix, or other local tumors considered cured by local treatment Persistent toxicity from previous treatments (including irAEs) that has not resolved to Grade 400 copies/mL (local lab assessment) Not receiving antiretroviral therapy Receiving established antiretroviral therapy for less than 4 weeks prior to the start of study treatment History of AIDS-defining opportunistic infections within 12 months prior to start of study treatment Patients with a history of HIV who do not meet any of the criteria above are eligible to participate but the patient must be under the care of an HIV/Infectious Diseases specialist or an HIV/Infectious Diseases specialist must be consulted prior to inclusion. Any severe or serious, acute or chronic medical or psychiatric condition or laboratory abnormality as per investigator's judgement that may increase the risk associated with trial participation or IMP administration, including ongoing or active infection requiring systemic antibiotics Further exclusion criteria apply.
